Abstract

In this paper the sequential identification approach outlined in [1]is employed to estimate the parameters of a bilinear hysteric model of the kinematic type. Emphasis is placed on the development of an estimation routine geared to bypass the difficulty originating from the indetermination of the identification problem in terms of the three parameters associated with the piecewise linear model employed. Numerical experimentation using simulated data is presented to show the feasibility and accuracy of the method. An additional example involving the modeling of a real steel frame tested on a seismic table is finally presented as a preliminary incursion into the field of modeling and identification of real structures.
